1968 '340' Barracuda vs 1968 '383' Road Runner

I have seen stock 383 Road Runners with 3.23s do that all day long.

Not in my neck of the wood's. In the DC area, the best running stock 3.23 cars were in the 14.75/14.90 range. My close neighbor had a column shift 3.23 car he bought new.........14.80's was his best, and spinning wasn't a problem on his car, even with 70 series belted tires.
